Project description:ob/ob mice is an obese mice. CIDE family proteins including Cidea, Cideb and Cidec play important role in lipid metabolism. Cidea is mainly expressed in the brown adipose tissue (BAT). Cidec is mainly expressed in the BAT and white adipose tissue (WAT). We generated ob/ob/Cidea-/-/Cidec-/- mice to investigate the phenotype of fat tissue. ob/ob/Cidea-/-/Cidec-/- mice are lean when compared with ob/ob mice. The tissue weight and TAG content of BAT and WAT was extreamly decreased in ob/ob/Cidea-/-/Cidec-/- mice compared with that in ob/ob mice. We next extract the total RNA from the BAT and WAT of ob/ob and ob/ob/Cidea-/-/Cidec-/- mice, to perform microarray analysis using Mouse Gene 1.0 ST array system, Affymetrix. We then analysised the up-regulated and down regulated pathways.

Project description:Obesity may promote myeloid cell accumulation in liver. Intravital liver tissue imaging revealed that the number of myeloid cells attached to sinusoidal wall significantly increased in ob/ob mice. To assess the pathophysiological roll of liver sinusoidal endothelial cells (LSEC) in obese livers, we performed microarray analysis in LSEC isolated from an 8-week-old wild-type and ob/ob mouse. Pathway analysis in microarray data shows genes related to cell adhesion, chemokine signaling and leukocyte transendothelial migration are upregulated in LSEC from ob/ob.

Project description:BACKGOUND: Drinking water can be contaminated with pharmaceuticals. However, it is uncertain whether this contamination can have harmful consequences for the liver, especially in the context of obesity. OBJECTIVES: To determine whether chronic, low dose exposure to pharmaceuticals could have deleterious effects in livers of lean and obese mice. METHODS: Lean and ob/ob male mice (5-week-old) were treated for 4 months with a mixture of 11 drugs (acetaminophen, caffeine, carbamazepine, cotinine, diclofenac, erythromycin, ibuprofen, phenazone, roxithromycin, salicylic acid and sulfamethoxazole) provided in drinking water at a concentration of 1 mg/L (for each drug). At the end of the treatment, investigations were performed in liver and plasma. RESULTS: Some liver and plasma abnormalities were observed in ob/ob mice treated with the cocktail containing 1 mg/L of each drug. For this dosage, a gene expression analysis by microarray showed altered expression of circadian genes (e.g. Bmal1, Dbp, Cry1) in lean and obese mice. RT-qPCR analyses carried out in all groups of animals indicated that expression of 8 different circadian genes was significantly modified in a dose-dependent manner. For some genes, a significant modification was observed for dosages as low as 100-1,000 ng/L. Drug mixture and obesity presented an additive effect on circadian gene expression. These data were confirmed in an independent study performed in female mice. CONCLUSIONS: Chronic, low dose exposure to pharmaceuticals disturbed hepatic expression of circadian genes, especially in obese mice. Because some of the 11 drugs can be found in the drinking water at such concentrations (e.g. acetaminophen, carbamazepine, ibuprofen) our data could be relevant in environmental toxicology, in particular for obese individuals exposed to these contaminants. C57BL/6J lean and ob/ob male mice (5-week-old) were treated for 4 months with a mixture of 11 drugs provided in drinking water at a concentration of 1 mg/L (for each drug). 4 groups were designed: untreated versus treated WT and ob/ob mice (n=6 mice per group).

Project description:GWAT store most of the TAG in mice, ob/ob mice is an obese mice. Ob/ob/Fsp27-/- mice are lean when compared with ob/ob mice. The GWAT weight was dramatically reduced in ob/ob/Fsp27-/- mice. We next extract the total RNA from the GWAT of ob/ob and ob/ob/Fsp27-/- mice, to perform microaary analysis using Mouse Genome 430 2.0 arrays, Affymetrix. We then analysised the up-regulated and down regulated pathways.

Project description:To identify novel transcriptional factors involved in dysfunctional hepatic lipids homeostasis in obesity, mRNA microarray analysis were performed to of livers of ob/ob mice, a widely used obese model, and C57BL/6J control mice. Chow-fed ob/ob and C57BL/6J mice were housed in a 12 h of light and 12 h of dark cycle and fed ad libitum a regular chow diet. Mice were sacrificed at 16:00 (Zeitgeber Time 8 during light phase). Total RNA was prepared from each liver using TRIzol (Invitrogen). Equal aliquots of total RNA from each of four mouse livers in each group were pooled and used for biotin labeling as described in the Affymetrix technical bulletin. Then the transcriptional profiles of samples were probed using the Gene-Chip Mouse Genome 430 2.0 arrays.
